| fungal diversity, dominance, and community structure in the rhizosphere of clonal picea mariana plants throughout nursery production chronosequences. | fungal diversity in the rhizosphere of healthy and diseased clonal black spruce (picea mariana) plants was analyzed with regard to nursery production chronosequences. the four key production stages were sampled: mother plants (mp), 8-week-old cuttings (b + 0), second-year cuttings (b + 1), and third-year cuttings (b + 2). a total of 45 fungal taxa were isolated and identified based on cultural, phenotypic, and molecular characters. members of phylum ascomycota dominated, followed by basidiomycot ... | 2007 | 17347891 |
